An accurate opinion on valuation, loosely held, will be of limited help. An incorrect opinion on valuation, strongly held, is far worse. This one statement shows how hard it is to get it all right.

Hasty opinion too often points the wrong way, and then affection for one's own opinion binds up the intellect.

If you give people a firm opinion, you run the risk of being wrong. Guess what? People remember when you’re wrong a lot more often than when you’re right. So the tendency is to include all the possibilities. It’s intellectually honest, even.

[...] each vulgar opinion, proved to be erroneous, is an approximation to truth [...].

Valuation is vague and arbitrary, when there is no assurance that it will be generally acquiesced in by others.

A valuation, which is established as the outcome of the mass psychology of a large number of ignorant individuals is liable to change violently as the result of a sudden fluctuation of opinion due to factors which really do not make much difference . . . since there will be no strong roots of conviction to hold it steady.

When you have a strongly held belief, don't you think it's important to express that belief accurately?

I have opinions of my own - strong opinions - but I don't always agree with them.

Opinions derived from long experience are exceedingly valuable, and outweigh all others, while they are consistent with facts and with each other; but they are worse than useless when they lead, as in this instance, to directly opposite opinions.

Opinions have no value, though the whole world is run on opinions. Opinions are limited. Your opinion, or my opinion, the opinions of the totalitarians, or the opinions of the church people and governments are all limited. Your judgments and opinions that give values are all limited. When you think about yourself from morning until night, as most people do, that is limited. When you say you are Swiss, or when you are proud to be British as though you are God’s chosen people, that is limited. So opinions are limited. When one sees that clearly, then one does not cling to opinions or the values that opinions have created, because your opinion against another opinion doesn’t bring about peace. That is what is happening in the world, one ideology against another ideology — communist, socialist, democrat, and so on. So please understand that if you are adhering to your opinion and I am sticking to mine, then we shall never meet.

There must be freedom from opinion and values so that we are actually not holding back our opinions and using them as axes to beat each other, to kill each other. Opinions are limited and therefore they must inevitably bring about conflict. If you hold on to your limited conclusions, and another holds his limited conclusions, experiences, then there must be conflict, wars, destruction. If you see that very clearly, then opinions become very superficial, they have no meaning. Don’t have opinions, but be free to inquire, and in that inquiry act. The very inquiry is action; it is not that you inquire first and then act, but in the process of inquiry you are acting.

First, if any opinion is compelled to silence, that opinion may, for aught we can certainly know, be true. To deny this is to assume our own infallibility. Secondly, though the silenced opinion be an error, it may, and very commonly does, contain a portion of the truth; and since the general or prevailing opinion on any subject is rarely or never the whole truth, it is only by the collision of adverse opinions that the remainder of the truth has any chance of being supplied.

Thirdly, even if the received opinion be not only true, but the whole truth; unless it is suffered to be, and actually is, vigorously and earnestly contested, it will, by most of those who receive it, be held in the manner of a prejudice, with little comprehension or feeling of its rational grounds. And not only this, but, fourthly, the meaning of the doctrine itself will be in danger of being lost, or enfeebled, and deprived of its vital effect on the character and conduct: the dogma becoming a mere formal profession, inefficacious for good, but cumbering the ground, and preventing the growth of any real and heartfelt conviction, from reason or personal experience.

Haven't you noticed that opinion without knowledge is always a poor thing? At the best it is blind — isn't anyone who holds a true opinion without understanding like a blind man on the right road?

clxxxiii Do not hold your Views too firmly. Every fool is fully convinced, and every one fully persuaded is a fool: the more erroneous his judgment the more firmly he holds it.
